15 Claims.

My invention relates to typewriting and like machines and moreparticularly to tabulator mechanism. More specifically stated theinvention relates to column stop bars and stops for use therewith.

The main object of my invention is to provide simple and inexpensive,yet highly eflicient devices of the character specified which may bereadily incorporated in existing typewriting machines, and may becombined with existing tabulator mechanism, without modifying, ormaterially modifying the existing structural features of such machines.

It is another object of my invention to provide an improved column stopbar or tabulator stop rack which will be possessed of greater strengthand rigidity than column stop bars heretofore used.

A further object of my invention is to so construct my improved columnstop bar that all the elements thereof will cooperate to produce greaterstrength in said bar.

Still another object of my invention is to provide an improved stopwhich may be eifectively held in either its projected or retractedpositions, and which may be readily inserted into said bar and movedeasily from one of said positions to the other.

To the above and other ends which will hereinafter appear, my inventionconsists in the features of construction, arrangements of parts andcombinations of devices set forth in the following description andparticularly pointed out in the appended claims.

In the accompanying drawing, wherein all of the views are on an enlargedscale and like reference characters designate corresponding parts in thedifferent views,

Fig. 1 is a fragmentary, vertical fore and aft sectional view throughthe upper rear portion of a typewriting machine in which my inventionhas been embodied;

Fig. 2 is a longitudinal vertical sectional view through the column'stopbar and taken along the line 22 of Fig. 1 and looking in the directionof the arrows at said line, the view showing the manner of attaching thecolumn stop bar to the carriage;

Fig. 3 is a fragmentary, horizontal sectional view taken along the line3-3 of Fig. 2 and looking in the direction of the arrows at said line;

Fig. 4 is a fore and aft, vertical sectional View through the colurnnstop bar taken along the line d@ of Fig. 2 and looking in the directionof the arrow at-said line, the view showing one stop in extended orprojected position and another stop in retracted position; and

Fig. 5 is a detail perspective view of a portion of the column stop barhaving the cover and stops 5 removed therefrom and showing the formationof the various slots or grooves in the body member.

My invention is shown, in the present instance, embodied in a No.Remington Noiseless machine in which the invention may be readily in- 10corporated without modifying, or materially modifying, the existingstructural features of said machine. Only a sufficient number of partsof said machine have been shown to illustrate the invention in itsembodiment therein. It should be understood, however, that the inventionis not restricted to embodiment in the machine referred to but may beapplied to typewriting and like machines generally, wherever foundavailable.

The carriage, which is designated as a whole by the reference numeral10, may be of the usual construction having a platen l I journalled inright and left-hand end plates l2 and I3 respectively. On the under sideof the carriage there is provided a cross bar or rail M, which may besecured 5 thereto in any suitable manner, and which is grooved toreceive crossed bearing rollers I5. These rollers 15 are also receivedin oppositely disposed grooves in a two-part guide rail l6 mounted forcase shifting movement and receiving such movement by the usual meanswhich include an arm l1. Thus, the carriage is supported and guided inits traveling movements from side to side of the machine under controlof its escapement and tabulator mechanism.

Each of the carriage end plates l2 and. I3 is provided with an inwardlyextending lug I 8, and these lugs I8 serve as supports for a tabulatorstop rack or column stop bar which is designated as a whole by thereference numeral 20. This column stop bar 20 comprises a main or bodyportion 2| and a separate cover plate or member 22 secured thereto in amanner that will be described in more detail hereinafter. Said columnstop bar 20 is adjustably secured to the lugs I 8 by means of screws 23which pass through elongated openings 24 provided in the ends of thecover member and received in tapped openings 25 in the lugs l8. Washers26 may be used to provide a bearing surface between the heads of thescrews 23 and the flat surface of the cover member 22 adjacent theelongated openings 24. When the column stop bar 20 is properly mountedupon the lugs l8 it may be secured against longitudinal displacementwith respect to said lugs by means of an adjustable set screw 21. Atendency for relative displacement between the carriage and the columnstop bar occurs only when the carriage is arrested by the cooperation'ofa projected tabulator stop with a column stop. Therefore, it isnecessary to provide a set screw 21 only at the right-hand end of thecolumn stop bar, or at the left-handrend as shown in Fig. 2.

As shown in Fig. 5, the body portion 2|. of the column stop bar, whichmay be cut from rectangular stock, is provided on its'under side with alongitudinal or extended channel or groove 28, said groove forming rearand forward flanges 29 and 30 on theunder sideof'said body member. Thepurpose of this groove is to lighten the entire construction and cut thecost of manufacture, as will hereinafter appear. However, this groove 28should not be so deepor wide as to materially weaken the construction ofthe body member.

The upper surface of the body member 2| is also provided with alongitudinal groove ,or channel 3| which forms rear and forward flanges32 and 33 for the reception of the cover member 22.. The channel orgroove 3| is shallower than the groove 28 but nevertheless is slightlydeeper than the thickness of the cover member 22 so that the flanges 32and 33 may bepressed or swedged in to firmly fasten the cover in place,as will hereinafter more clearly appear. In order that the scribed aboveas being provided in the top and bottom surfaces of the body member 2|,said body member isprovided with a group of transverse, or fore and aft,slots or notches .31 which form comb teeth 3'1 in said body member. 7These slots are cut at letter space intervals, which may be either, sayfor example, IO'or |2.to the inch depending on' whether the machine isprovided with pica or elite? type, and extend from the top of thebodyvmember through the flanges 32 and 33 and into the flanges 29 and-36,- asclearly shown in Fig. 5. In the present instance, I have shown twelve ofthe slots 3'1 to the inch, and each slot has parallel sides so that itmay form a guideway for'the reception of a column stop'a's no tendencyto move from-side to side in the 7 slots.

The cover member 22 which fits into the shal low cut 3! in the top ofthe body member 2! is slightly longer than said body member and, as

explained above, is provided with the elongated openings 24 near theends'thereof to facilitate in attaching the assembled column stop bartothe 'lugs I8 provided onthe carriage. The forward edge ofthe covermember is straight and abuts the flange 33 when mountedin the shallowchannel 3| of the body member. The rearward edge, however, is providedwith teeth 38 which'are' 'cut to match the slots3'l in the body member,so that when the cover member. is properly mounted,

stantially V-shaped longitudinal cut or groove 39 which is adapted tocooperate with a spring detent provided on each of the column stops, aswill hereinafter more fully appear.

When constructing and assembling the column 5 38 registering andinterlocking with the slots 31 15 adjacent the rear flange 32. Finally,the forward edge of the flange 32 is pressed, swedged or staked asindicated at 40, and the rearward edge of the flange 33 is similarlypressed or swedged as indicated at 4| to firmly lock the cover in itsproper. position in the groove 3! and complete the assembly of thecolumnstop bar 29. The above described construction and assembly of thecohunn stop bar 28, with the longitudinal grooves in the upper and lowersurfaces of the body member and the cover member 22 swedged in the uppergroove 3! with the teeth 38 thereon registering or interlocking in theslots 31, is such as to strengthen the assembled column stop bar andrender it rigid and none the less weakened by 30 the close relation ofthe slots 31 provided in the body portion. In other words, it will beseen that the-comb teeth 3'! intervening between the slots 3! arerigidly united at the lower ends thereof by the integral flanges 29 and30, whereas the upper free ends of said teeth are firmly connect- 'ed toand interlocked with the teeth 38 of cover plate 22 which plate in turnis firmly connected to and reinforces the body member 2! of the stopbar[ It will be seen, moreover, that the upper 40 end of "each combtooth 31* has a swedged connection at 40, M with the cover plate toprovide an additional firm connection between the free fend of each combtooth 31 and the cover plate.

Thus; it will be apparent thatthere is an interlocking between the coverplate and comb teeth in two directions at right angles to each other.

Furthermore, it'Will be apparent that any pressure applied to theassembled column stop bar, which would tend to bend it, is resisted bythe strengthening eifect of the cover member 22 mounted and lockedin'the upper longitudinal groove 3|. In actual practice it has beenfound that the above described construction of column stop bar ispossessed of greater rigidity than most bars ofthis same general typeand the danger of twisting or collapse, as is present in hollow tubesfor example, is in fact, entirely avoided.

7 'Having thus described in detail the construction of my improvedcolumn stop bar, I shall-now describe an improved form of column stopspecially designed for use in combination therewith. Referring nowparticularly to Figs. 1 and l, it willbe observed that my improvedcolumn stop, which is designated as a whole by the reference numeral 44,comprises a'thin blade-like mem-' ber of substantially the samethickness as the slots 31, but enough thinner so as toallow said stoptohave a firm sliding fit with the inner surfaces of the slot in whichit is mounted. A spring detent member 45 may be formed integral with theupper edge of the column stop 44 in the same v[plane as the body portionthereof by cutting a longitudinal slot or indenture 43 in said stopclose to and parallel with the upper edge thereof. The

resiliency of the spring detent member 45 of course depends upon thecloseness of the slot 46 to the upper edge of the column stop 44, andalso upon the length of the slot 46, said slot in the present instanceextending practically the entire length of the stop 44. A substantiallyinverted V-shaped detent tooth or projection 41 may be formed on theupper edge of the spring detent 45 adjacent the right-hand end thereof(as the parts are shown in Fig. 4) to engage or be received in the V-shaped longitudinal groove 39 when the column stop 44 is in itsprojected position, as shown in Fig. 1. When the stop is in itsprojected position, it is prevented from further rearward movement bycontact of a perpendicular stop portion 48 on the free end of the detent45 with the forward edge of the cover member 22. When the stop 44 is inits retracted position it is held against accidental displacement orfurther forward movement therefrom by contact of a stop lug 59 with theassociated tooth 38 on the cover plate 22. In its retracted position thedetent tooth 41 abuts the forward edge of the cover member 22 toresiliently hold the stop 44 in this position.

It will be observed that the height of the stop portion 48 is slightlygreater than the height of the detent tooth 41. Thus, in order to insertor Withdraw a column stop from a slot 31 the spring detent .5 will haveto be depressed a greater degree than is required when moving the stopfrom retracted to projected position. To allow this greater depressionof the spring detent 45, the outer edges of the slot 48 may be sloped asindicated at in Fig. l. Furthermore, the righthand edge (Fig. 4) of thestop portion 48 may be inclined as indicated at 52 to aid in the easyinsertion of one of the column stops 44 into a slot 31. In this mannerthe stops may be readily assembled on or detached from the stop bar,when desired, without removing the cover plate 22.

Referring to Fig. 4, it will be seen that the degree of slope of thesides of the V-shaped groove 39 is somewhat less than the degree ofslope of the V-shaped detent tooth 41. Such a construction allows acomparatively easy movement of the stop 44 from its retracted toprojected posi tion or vice versa due to the camming effect of the wallsof said slot on the detent projection 41. It has been found practical tohave the degree of slope of the sides of the projection 41 substantially30 degrees, and thus the degree of slope of the walls of the V-shapedgroove 39 would be less than 30 degrees.

When the column stop bar 20 is equipped with a column stop 44 in each ofthe slots 31 and properly mounted upon the carriage of the typewritingmachine, there will be one column stop 44 for each letter space positionof the carriage throughout the extent of its movement. Normally thestops are in their retracted position, but they may be set or moved toprojected position in any suitable manner, such for example, as by theuse of a key actuated setting lever 53, as shown in Fig. 1. This lever53 is pivoted at 54 to a bracket 55 which may be secured to the underside of the guide rail l6, and has an actuating or a setting movement ina counter-clockwise direction (Fig. 1). The lever 53 is actuated bymeans of a link 55 which may be controlled from a key in the keyboard ofthe machine if desired. The construction and arrangement are such thatwhen the setting key is depressed, said lever 53 will be turned in acounter-clockwise direction, as shown in Fig. 1, to move a stop oppositeor in line with it from retracted to projected position.

It will be understood, of course, that the selection of the stop whichis moved to projected position in the manner described above will dependupon the position of the carriage in its line of travel. 5

When a column stop 44 is in its'projected position, it is adapted tocooperate with the usual counter or tabulator stop or stops. One ofthese stops which is shown at 51 is pivoted at 58 to the usual tabulatorframe 59 at the rear of the machine. The tabulator stop 51 is controlledfrom a tabulato-r key (not shown) situated in the keyboard of themachine, and by depression of such a tabulator key may be moved from thefull-line to the dotted line position shown in Fig. l. Dv" pression of atabulator key also releases the carriage from control of its escapement(by means not shown) so that it will move to the left freely under theurge of its spring drum (not shown) until the projected column stop 44contacts the actuated counter or tabulator stop 51.

My improved column stop bar and column stop may also function incombination with a clearing lever 60 which is adapted to return theprojected column stops to their normal retracted positions. This leveris similar in shape to the tabulator stop 51 and like said lever ispivoted at 58 to the tabulator frame 59, and is controlled through alink 61 from a key in the keyboard of the machine. The clearing lever 89is different from the tabulator stop 51, however, in that it is thickerin construction and is provided with a curved edge 62 having a beveledor cam face 53-on the left-hand side thereof. The construction of saidclearing lever 60 is such that when the clearing key is de pressed saidlever will be moved in a clockwise direction, as shown in Fig. 1, toforce any projected column stops 44, which may be in line with it, backto retracted position. If several stops are in projected position, andthe carriage is, say, in its extreme left-hand position, all of theprojected stops may be moved to retracted position by depressing andholding the clearing key in depressed position and moving the carriageto the right. In doing this the beveled surface 63 acts as a cam to moveeach projected column stop that it may contact during the travel of thecarriage to the right, from its projected to retracted position.

From the foregoing description it will be apparent that by means of myinvention I have provided a simple and inexpensive, yet highly efficientcolumn stop bar and column stop construction which may be readilyincorporated in existing typewriting machines, and may be combined withexisting tabulator mechanism, without modifying, or materially modifyingthe existing structural features of such machines. It will also beapparent that by my invention I have provided an improved column stopbar which is possessed of great strength and rigidity, and a column stopfor said bar which may be effectively held in either its projected orretracted position, and which, moreover, may be readily inserted into ordetached from said bar when desired and moved 65 easily from one of saidprojected or retracted positions to the other.
